<Outline of configuration>
FIG. 1 is a diagram illustrating a charging system control device 2000 according to the first embodiment, together with the use environment thereof. The charging system control device 2000 controls the charging system 3000. The charging system 3000 charges the electric vehicle 6000 using the power received from the external power supply 5000 according to the control of the charging system control device 2000. Here, the solid arrow represents the flow of power, and the dotted arrow represents the flow of information.

  The charging system control device 2000 includes a control instruction transmission unit 2020, a charging characteristic information acquisition unit 2040, and a region information acquisition unit 2060. The area information acquisition unit 2060 acquires area information having a maximum received power function that represents time dependency of power that can be supplied to the charging system 3000 by the external power supply 5000. The area information is determined by the area where the external power supply 5000 is located. The charging characteristic information acquisition unit 2040 acquires charging characteristic information having one or more charging characteristic functions representing a time change of charging power necessary for charging the electric vehicle 6000 between the start and end of charging of the electric vehicle 6000. To do.

  The control instruction transmission unit 2020 selects one of the plurality of charging characteristic functions based on the area information, and sets the charging system 3000 so that the charging system 3000 transmits power to the electric vehicle 6000 according to the selected charging characteristic function. Control. Specifically, one charging characteristic function whose power value is always equal to or lower than the maximum received power function is selected from a plurality of charging characteristic functions. Then, a control instruction is sent to the charging system 3000 according to the selected charging characteristic function, so that the charging system 3000 receives power from the external power supply 5000 according to the charging characteristic function.

  The charging system 3000 includes a control unit 3020 and a charging unit 3040. The control unit 3020 receives the control instruction from the control instruction transmission unit 2020 and controls the power received by the charging unit 3040 from the external power supply 5000 according to the received control instruction. Charging unit 3040 transmits the received power to electric vehicle 6000 and charges electric vehicle 6000. By doing so, the charge completion time in the charge characteristic function becomes the charge completion prediction time.

  An example of the charging characteristic function is shown in FIG. The charging characteristic function requires a large amount of power in the first half of the charging period as in the charging characteristic function 1, the charging power is always small as in the charging characteristic function 2, and the charging power in the latter half of the charging period as in the charging characteristic function 3 There are various things such as larger ones, and the time required for charging also varies.

  FIG. 3 shows an image of processing for selecting the charge characteristic function. The graph on the upper left of FIG. 3 shows the maximum received power function obtained from the area information. The other graph on the left side of FIG. 3 is a charge characteristic function included in the charge characteristic information. And the result of comparing these is the right side of FIG. As a result of comparison, the charging characteristic function 2 has a power value that is always less than or equal to the maximum received power function. Therefore, if the electric vehicle 6000 is charged according to the charging characteristic function 2, the electric power required for charging is always less than or equal to the electric power supplied from the external power supply 5000. Therefore, the electric vehicle 6000 is supplied with the electric power supplied from the external power supply 5000. Can be charged. On the other hand, the charging characteristic function 1 is larger than the maximum received power function in the first half of the charging period, and the charging characteristic function 3 is larger in the second half of the charging period. Therefore, when the electric vehicle 6000 is charged using these two charging characteristic functions, power is insufficient during charging. Therefore, in this example, the control instruction transmission unit 2020 selects the charging characteristic function 2 from these three charging characteristic functions.

  As described above, the charging system control apparatus 2000 acquires the time dependency of the power supplied from the external power supply 5000 determined by the region where the external power supply 5000 is located, and the power value is always less than the power that can be supplied from the external power supply 5000. A certain charge characteristic function is selected. Charging system control apparatus 2000 controls charging system 3000 and transmits electric power according to the selected charging characteristic function to electric vehicle 6000. In this way, the charging system control apparatus 2000 can accurately predict the charging completion time by performing charging in consideration of regional information.

  Hereinafter, the details of the configuration and operation of the charging system control apparatus 2000 according to the first embodiment and its use environment will be described.

<Details of configuration>

The control instruction transmission unit 2020 controls the charging system 3000 based on the selected charging characteristic function from the start to the end of charging. Therefore, the control instruction transmission unit 2020 creates a power equipment operation plan representing a plan for controlling the charging system 3000 based on the selected charging characteristic function, and stores it in the operation plan storage unit 2070. During the charging period, the charging system 3000 is controlled while referring to the power equipment operation plan stored in the operation plan storage unit 2070.

The maximum received power table 200 represents the correspondence between time and power in the maximum received power function in a list format, and includes, for example, a time 202 and a maximum received power 204. Maximum received power 204 represents power that can be supplied from external power supply 5000 to charging unit 3040 at each time 202.

<Details of charging characteristics information>
The charging characteristic function included in the charging characteristic information is a function that represents a time change in the amount of electric power that needs to be charged to the electric vehicle 6000 per unit time from the start to completion of charging of the electric vehicle 6000. The electric vehicle 6000 has characteristics specific to the vehicle type in terms of the total electric energy required for charging (hereinafter referred to as required electric energy), charging electric power, and charging completion time, and the charging characteristic function is determined by these characteristics. The charging characteristic function depends on the storage battery and the charging circuit in the electric vehicle 6000. There are a plurality of charging characteristic functions for each vehicle type, and the electric vehicle 6000 can be charged by transmitting electric power to the electric vehicle 6000 according to one of the charging characteristic functions. However, the charging characteristic function that can be used for charging may be limited by the amount of required power, the limit of power that can be used, external factors such as temperature, and the like. Therefore, the charging characteristic information acquisition unit 2040 acquires, as charging characteristic information, a charging characteristic function that meets a condition such as a required power amount among one or more charging characteristic functions corresponding to the electric vehicle 6000.

  The charge characteristic information includes, for example, a charge characteristic information table 100 shown in FIG. The charging characteristic information table 100 represents the relationship between time and power in each charging characteristic function in a list format, and has, for example, a characteristic ID 102, an elapsed time 104, and a power 106. The characteristic ID 102 is an ID of each charging characteristic function. For each charging characteristic function, the electric power required for charging at the time represented by the elapsed time 104 is represented by electric power 106.

<Details of power equipment operation plan>
The control instruction transmission unit 2020 creates a power equipment operation plan based on the selected charging characteristic function. Specifically, the power equipment operation plan has a received power function that represents a temporal change in power that the charging unit 3040 receives from the external power supply 5000. In the present embodiment, since all of the received power is transmitted to the electric vehicle 6000, the selected charging characteristic function is directly used as the received power function.

  The received power function is represented, for example, as a received power table 400 shown in FIG. The received power table 400 represents changes in time and power in the received power function in a list format. For example, the received power table 400 includes a time 402 and a received power 404 representing the received power at each time.

<Overall Control Flow by Charging System Controller 2000>
FIG. 7 shows the overall flow of processing in which the charging system control apparatus 2000 controls the charging system 3000.

  First, in step S <b> 102, the control instruction transmission unit 2020 creates a power equipment operation plan and stores it in the operation plan storage unit 2070. Details of the flow of this operation will be described later.

  Next, in step S104, the charging completion scheduled time determined by the electrical equipment operation plan is notified to the user. There are various methods for notifying the user of the estimated charging completion time. For example, a method for displaying a charging completion time by installing a display device in the charging system control device 2000, a method for displaying a charging completion time by installing a display device in the charging system 3000, data communication with the vehicle, There are a method of displaying on a display device included in a navigation system, a method of performing data communication with a terminal such as a mobile phone held by a user, and a method of displaying on the display device.

  Next, in step S106, the control instruction transmission unit 2020 controls the charging system 3000 based on the power equipment operation plan, and charges the electric vehicle 6000.

<Power Equipment Operation Plan Creation Processing by Control Instruction Transmitter 2020>
FIG. 8 shows a flow of a power device operation plan creation process performed by the control instruction transmission unit 2020 in step S102 of FIG.

  First, in step S202, the control instruction transmission unit 2020 acquires charging characteristic information from the charging characteristic information acquisition unit 2040. There are various methods for acquiring charging characteristic information by the charging characteristic information acquiring unit 2040. For example, it receives information on the vehicle type of the electric vehicle 6000 and the input of the required electric energy, and accesses and acquires a database storing charging characteristic information based on them, or charging based on the vehicle type and the required electric energy There is a method in which an administrator of the system control device 2000 manually inputs. Further, the information on the vehicle type and the required power amount may be automatically acquired from the electric vehicle 6000.

  Next, in step S <b> 204, the control instruction transmission unit 2020 acquires area information from the area information acquisition unit 2060. There are various methods for acquiring regional information by the regional information acquiring unit 2060. For example, there are a method of obtaining by accessing a management server that manages the power status of the area, a method of obtaining by receiving manual input by the administrator of the charging system 3000, and the like. Further, the information obtained from the area information is not limited to the maximum received power function. For example, the time dependency of the power price may be acquired as the regional information. In this case, for example, the maximum received power function is calculated based on the fluctuation of the power price.

  Next, in S206, i representing the ID of the charging characteristic function acquired from the charging characteristic information table 100 is initialized to 1. Hereinafter, the charging characteristic function with ID i is represented as charging characteristic function i.

  Steps S208 to S214 are loop processing performed for each charging characteristic function i. First, in step S208, it is checked whether i is equal to or less than the number of charge characteristic functions included in the charge characteristic information table 100. If i is equal to or less than the number of charge characteristic functions, the process proceeds to step S210. When i is larger than the number of charge characteristic functions, the process is finished for all the charge characteristic functions i, and the loop process is finished.

  In step S210, the charging characteristic function i is acquired from the charging characteristic information table 100. Specifically, all the records of the charge characteristic information table 100 whose characteristic ID 102 is i are acquired.

  In step S212, it is checked whether the charging characteristic function i is always equal to or lower than the maximum received power function. Specifically, it is determined whether the power 106 is less than or equal to the power value of the maximum received power function for all records acquired in step S210. If the charging characteristic function i is always less than or equal to the maximum received power function, the process proceeds to step S216. On the other hand, if the power 106 is greater than the maximum received power function in any record, the process proceeds to step S214. Step S214 is the end of the loop process starting from step S208, i is incremented by 1, and the process returns to step S208.

  In step S216, the charging characteristic function i is selected as a charging characteristic function to be used for charging the electric vehicle 6000. In step S218, a power equipment operation plan is created based on the charging characteristic function i. Specifically, in the present embodiment, the charging characteristic function i is a received power function that represents a temporal change in power that the charging unit 3040 receives from the external power supply 5000. Then, the received power function is stored in the operation plan storage unit 2070 as a power device operation plan.

  As described above, the charging process is selected by repeating the loop processing from step S208 to step S214, and a power device operation plan is created based on the selected charging characteristic function.

  When the power device operation plan creation process is completed without passing through step S216 and step S218, the electric vehicle 6000 cannot be charged with electric power that can be transmitted from the charging system 3000 to the electric vehicle 6000. There are various processes to be performed in this case, and for example, a process of notifying an error to the user of the charging system 3000 or the administrator of the charging system control apparatus 2000 can be considered.

<Control of Charging Unit 3040 by Control Unit 3020>
Control unit 3020 controls charging unit 3040 in accordance with the control performed by control instruction transmission unit 2020 in step S106. An example of a specific method is as follows. The control instruction transmission unit 2020 transmits the value of the received power 404 held by each record to the control unit 3020 at the time indicated by each record of the received power table 400 stored in the operation plan storage unit 2070. The control unit 3020 controls the charging unit 3040 so that the charging unit 3040 receives power of the magnitude indicated by the received power 404 from the external power supply 5000.

  Control instruction transmission unit 2020 may send a plurality of records stored in received power table 400 to charging unit 3040. In this case, the control unit 3020 controls the charging unit 3040 when the time indicated by each record in the received power table 400 is reached.

<Action and effect>
With the above configuration, according to the present embodiment, the charging system control device 2000 acquires the time dependency of the power supplied from the external power supply 5000 determined by the area where the external power supply 5000 is located, and the power value is always set to the external power supply 5000. By selecting a charging characteristic function that is less than or equal to the power that can be supplied from the vehicle and charging the electric vehicle 6000 based on this charging characteristic function, the charging completion time can be accurately predicted.

<Details of power equipment operation plan>
The power equipment operation plan according to the second embodiment includes a received power function representing a time change of power received by the distribution unit 3080 from the external power supply 5000, a charge / discharge power function representing a time change of charge / discharge by the power storage unit 3060, and a distribution unit. 3080 has a power transmission function between the distribution unit and the charging unit that represents a time change of the power transmitted to the charging unit 3040.

  The received power function is, for example, equal to the maximum received power function.

  The charge / discharge power function is obtained, for example, by subtracting a charge characteristic function used for charging the electric vehicle 6000 from the maximum received power function. In this case, when the value of the charge / discharge power function is positive, power is transmitted from the charging unit 3040 to the power storage unit 3060 to charge the power storage unit 3060. When the value of the charge / discharge power function is negative, the power storage unit 3060 Electric power is supplied from power storage unit 3060 to charging unit 3040 by discharging. FIG. 11 is a diagram illustrating an image of the calculation method of the charge / discharge power function. The upper part of FIG. 11 represents a comparison between the charge characteristic function and the maximum received power function, and the lower part of FIG. 11 represents the charge / discharge power function calculated from the above two functions. In FIG. 11, in the first half of the charging period, since the charging characteristic function is larger than the maximum received power function, power is discharged from the power storage unit 3060. Therefore, the charge / discharge power function takes a negative value. On the other hand, in the second half of the charging period, the maximum received power function is larger than the charging characteristic function, so that power storage unit 3060 is charged with power. Therefore, the charge / discharge power function takes a positive value.

  The charge / discharge power function is represented as, for example, a charge / discharge power table 300 shown in FIG. The charge / discharge power table 300 represents the relationship between time and power in the charge / discharge power function in a list format. The charge / discharge power table 300 includes, for example, time 302 and charge / discharge power 304 representing the charge / discharge power of the power storage unit 3060 at each time. For example, the charge / discharge power 304 indicates that charging is performed when the value is positive, and discharging is performed when the value is negative, and the magnitude of the power is represented by an absolute value of the charge / discharge power 304.

  The transmission power function between the distribution unit and the charging unit is determined based on the received power function and the charge / discharge power function. Specifically, for example, it is obtained by subtracting the value of power transmitted from the distribution unit 3080 to the power storage unit 3060 from the power value of the received power function. Here, the power transmitted by distribution unit 3080 to power storage unit 3060 is the power value when the power value of the charge / discharge power function is positive, and is 0 when the power value is negative.

  The transmission power function between the distribution unit and the charging unit is represented, for example, as a transmission power table 800 between the distribution unit and the charging unit shown in FIG. The power transmission table 800 between the distribution unit and the charging unit includes, for example, a time 802 and a transmission power 804 indicating the magnitude of power transmitted from the distribution unit 3080 to the charging unit 3040 at the time 802.

Specifically, a function obtained by adding the maximum storage battery power function included in the storage information and the maximum received power function included in the area information is defined as the maximum usable power function.

  In step S312, it is determined whether the charging characteristic function i is always the maximum usable power function. If the charging characteristic function i is always the maximum usable power function, the process proceeds to step S216, and if not, the process proceeds to step S214.

  In step S218, a power equipment operation plan is created based on the charging characteristic function i and the maximum received power function.

<Determining the maximum usable power in consideration of surplus power>
When the charging system control device 2000 according to the present embodiment selects the charging characteristic function, the charging system control device 2000 obtains power of a magnitude obtained by removing the surplus power representing the surplus power to be given to the charging unit 3040 from the power supplied to the charging unit 3040. It is assumed that the power can be transmitted from the charging unit 3040 to the electric vehicle 6000. Specifically, based on the power obtained by removing the surplus power from the maximum received power function in step S212 in FIG. 8 and from the maximum usable power function in step S312 in FIGS. Make a selection.

Here, a specific example of the method for obtaining the maximum received power function in consideration of the surplus power in step S212 in FIG. Here, multiplying the surplus power function means that a certain percentage of the maximum received power function is the surplus power. Also, subtracting the surplus power constant means giving the surplus power as a constant. In Equation 2, the maximum usable power can be obtained in consideration of the surplus power in Step S312 of FIGS. 13 and 16 by replacing the maximum received power function with the maximum usable power function.

<Overview>
The charging system control apparatus 2000 according to the eighth embodiment and the usage environment thereof are represented, for example, in FIG. 1, FIG. 9, FIG. 14, FIG. Since each configuration has already been described, description thereof is omitted.

  When the regional information is changed, the charging system control apparatus 2000 according to the present embodiment determines whether it is necessary to change the charging characteristic function used for charging, and if necessary, changes the power equipment operation plan. Do. First, a new maximum usable power function is obtained based on the changed area information. Here, if the new maximum usable power function is equal to or greater than the maximum usable power function before the change, it is possible to receive more power than the current state, so there is no need to change. On the other hand, if the new maximum usable power function is smaller than the maximum usable power function before the change at any time, the charging power may be insufficient at that time. Therefore, it is checked whether the new maximum usable power function is always equal to or higher than the currently used charging characteristic function. If the new maximum available power function is always greater than or equal to the current charge characteristic function, charging can continue with the current charge characteristic function. On the other hand, if the new maximum usable power function is smaller than the current charging characteristic function in any time zone, the charging power is insufficient in that time zone. Therefore, the charging characteristic information is acquired again, and a charging characteristic function whose power value is always lower than or equal to the new maximum usable power function is newly selected.

  As described above, even when the regional information is changed, the charging completion time can be accurately predicted. First, when charging is possible with the current charging characteristic function, the charging characteristic function is not changed, so the charging completion time is not changed. When charging cannot be performed with the current charging characteristic function, a new charging completion time can be accurately predicted by newly selecting an appropriate charging function.

<Details of power equipment operation plan change processing>
FIG. 19 shows a flow of the charging characteristic function changing process in the eighth embodiment. First, in step S502, the changed area information is acquired. In step S504, the current power storage information is acquired. In step S506, the changed maximum usable power determined based on the area information and the power storage information is compared with the charging characteristic function currently used for charging. If the maximum usable power function after the change is always greater than or equal to the charge characteristic function, there is no need to change the power equipment operation plan. Therefore, the power device operation plan change process is terminated. On the other hand, if the maximum usable power function is smaller than the charging characteristic function at any time, it is necessary to change the power equipment operation plan. Therefore, the process proceeds to step S508, and a new power equipment operation plan is created.

  The power equipment operation plan is created in step S508, for example, according to the flow shown in FIG. However, since the area information and the power storage information have already been acquired in step S502 and step S504, step S204 and step S301 are not performed.

With the above configuration, according to the present embodiment, the charging system control device 2000 charges the electric vehicle 6000 in consideration of the time dependency of the power supplied from the external power supply 5000 determined by the region where the external power supply 5000 is located. By performing, the charging completion time can be accurately predicted. Furthermore, even when the regional information is changed, the charging completion time can be accurately predicted.
